I'm new to linux. So bear with me. How do I upgrade my HDD install of DSL?

I don't think you can. John has said there is no way of doing it smoothly, which is a shame. I'm hoping he will post somewhere on this forum on how to switch the old KDrive servers for the new ones. Mounting the compressed image inside the ISO over a network (try doing that on Windows!) is relatively easy, so accessing the files isn't a problem for me. I just don't want to break anything. Actually, thinking about the fact that you can mount the image, maybe John could make a small script that would mount the image then copy the required files across. Not sure how well this would work with X running, though.
